Definitions
- the invention relates to a method and a device for hot repairing the heating cables of a coke oven battery according to the preamble of claim 1 and claim 5.
- the object of the invention is to improve the method for heating the heating cables in such a way that satisfactory heating properties are achieved with simplified technology.
- heating of the already completed sections of the respective heating train takes place during the bricking up of the heating trains.
- an air reversing device that moves along with the masonry is installed in the flow path.
- This air reversing device consists, on the one hand, of known cover plates, which prevent mortar, dirt or other things from falling in during the heating pass, and, on the other hand, of at least one air transfer pipe which bypasses the binder wall lying between at least two heating passes in the region of its mouth ends the cover plates breaks through and fluidly connects the at least two heating cables.
- a slider for regulating the flow of the combustion air is preferably installed in an air supply tube.
- the regenerator of the coke oven preheated air to the already bricked up parts of the heating trains. This air is drawn through the already built-up heating element and via the air reversing device into a falling heating element and back towards the regenerator. The air is drawn from the regenerator through the flue gas duct to the chimney and then escapes into the atmosphere.
- the combustion gas supply to the heating trains under repair remains interrupted, so that via the flow path of the heating media (air and gas) of a heating train, only the combustion air flowing through the regenerator absorbs a certain amount of heat and releases it again to the newly installed heating trains to be heated.
- the combustion air is used as a heat transfer medium. In this way, simple and energy-efficient heating of the freshly bricked masonry is achieved.
- the air reversing device With the progress of the masonry work, the air reversing device is gradually set higher, so that the newly bricked parts of the heating train are heated accordingly.
- the air reversing device is designed so that 4-6 layers can be bricked up.
- the control of the combustion air flow is carried out with the control elements already present on the coke oven. To precisely regulate the combustion air flow and thus the temperature in the already completed sections of the heating trains to be repaired z. B. by means of a slide in the direction of air reversal. The temperature is through
- Temperature measuring points which are arranged, in particular below, the air reversing device are controlled.
- FIG. 1 shows a vertical section through several pairs of twin heating trains in which two air reversing devices are arranged, in a schematic illustration
- Fig. 2 shows a vertical section through several Schuuch ⁇ pairs in which a second embodiment of the air reversing device is arranged with the three
- Heating trains can be heated in the same representation as in Fig. 1;
- FIG. 3A shows an enlargement of a section through an air reversing device according to FIG. 1 (section along the line
- FIG. 3B the same air reversing device in plan view (section along the line III B - III 3B of FIG. 3A).
- 1 shows a section through two pairs of heating cables 1 and 2 to be repaired.
- an air reversing device 3 with air transfer tubes 4 and 4 ', is arranged in each case.
- the Luftuberleitrohre 4 and 4 ' are gas-tightly connected at their lower end with cover plates 17, 17', which separate the prefabricated part of the heating elements 1 and 2 from the part still to be bricked up.
- the air transfer tubes 4 ' are each provided with a slide 5, with which the amount of air for setting the desired temperature of about 250 ° C below the air reversing device 3 can be controlled.
- the temperature below the air reversing device is measured with thermocouples 6.
- the flow path of the combustion air is shown by arrows.
- arrow 7 (FIGS. 1 and 2)
- the combustion air flows into the regenerator channel 23, flows through the regenerator 8 and enters the pair of heating cables 1 to be repaired at the burner level 9.
- the combustion air then flows through the air reversal pipes 4 and 4 'and flows in the descending heating train 1 via the burner level 10 into a neighboring regenerator 11 and exits there via the regenerator channel 23 according to arrow 12 to the chimney.
- the flow velocity of combustion air is determined by the chimney draft, as well as by adjusting the Rege Lama doors of the coke oven, the non Darge in FIG. 1 ⁇ is shown. A further control of the combustion air flow is carried out with the slide 5 of the air reversing device 3.
- FIG. 2 shows a vertical section through three new heating elements 14, 15 and 16 to be walled up.
- the air reversing device 3 consists of more parts.
- the air transfer tubes 4, 4 ′ and 4 ′′ are inserted into an intermediate part 13 plugged in.
- the air transfer pipes 4 ′′ and 4 ′ are each provided with a slide 5.
- the remaining reference numerals have the same meaning as m in FIG. 1.
- the combustion air flows through the central heating train 14 upward through the air reversing device 3, is distributed in the falling heating trains 15 and 16 and flows again via the regenerator 8 to the corresponding exhaust gas valves the coke oven. After switching over the regenerator, the combustion air flows upward in the heating elements 15 and 16 according to the bracketed arrows, is sucked off via the heating element 14 and flows through the regenerator 8 to the corresponding flue gas valve of the coke oven.
- the air reversing device 3 shows the exact arrangement of the air reversing device 3 m from the heating trains to be repaired, which consist of the binder walls 19 and the runner walls 24.
- the air reversing device consists of the air guide tubes 4 and 4 ', which are connected gas-tight to the cover plates 17, 17', the air guide tubes 4 and 'are inserted into one another with their horizontal ends and by means of at least one lock 18, which is on the cover plate 17, 17 'is arranged, each m the joints of the heating brickwork locked.
- this is z. B. wrapped in insulating wool 20.
- the cover plates 17 should also be covered with insulating wool 21 on their underside. This also improves the seal to the girder walls 19 and the runner walls (24).
- the flow through the air reversal device 3 is represented by the arrows 22; The system changes according to the heating changeover of the coke oven battery and the changeover period in about 20 minutes.
